Hi all,

I did driving test of my mowbot this morning and it needs some improvement. My platform is based
on Black&Decker cordless mower with rear wheels independently driven and front caster wheels. Due
to the rigidity of frame mower occasionally looses traction of one of the driving wheels. I'm
considering two options:

1. Tricycle with single front caster - stability shouldn't be a problem, since wheelbase is really
large, but cutting height regulation will suffer.

2. Independent suspension for front casters (swivel) - allows to limit tilt of bar with casters,
so cutting height variations can be limited, but traction still can be lost when casters reach
limit of their travel.

I would gladly hear any advice you may have. Thanks.
